Backyard Aquaponics
A place to discuss aquaponics

It occurred to me the other day that I hadn't posted how I measure pH.

Nothing special but these dip sticks work brilliantly.





We get them as part of a package of medical goods but you can buy them at chemists.

What's a rough cost for them?

Why use the kit with resolution of only pH1 and a far greater range than ever seen in AP (pH0-14), when they sell kits covering the pH6-8 range with pH 0.2/03 resolution? My personal preference is to accurately know my pH.
You could have a decent pH meter with better resolution for the cost of a couple of packets of those strips.

I used to use the solution in the test kit but would get annoyed because I'd have to test twice if the pH was close to 7.

I use them for my BY system mostly because they are free.

Sorry Arbe don't know the cost.
